After all the talk of PRIDE star Wanderlei Silva filling in for Gustafsson turned out to be an elaborate April Fool's joke, White revealed Tuesday evening that Ilir Latifi has been tapped as the replacement.

Latifi is a training partner of Gustafsson and enters the main event fight with a record of 7-2-1, winning four of his last five fights.

His sole loss during that span came to current Bellator Light Heavyweight Tournament winner Emmanuel Newton in a bout under the Shark Fights banner during 2011.

"The Sledgehammer" faces a stiff test in Mousasi, currently undefeated (5-0-1) in his past six fights and holding wins over Hector Lombard, Melvin Manhoef, Mark Hunt and Ronaldo Souza in his 10-year career.
